Reducing Annotation Burden Through Multimodal Learning

This study examined deep learning-based multimodal fusion techniques for the combined classification of radiological images and associated text reports, comparing the classification performance of three prototypical multimodal fusion techniques. The experiments demonstrate the potential of multimodal fusion methods to yield competitive results using less training data than their unimodal counterparts. This suggests that the potential of multimodal learning decreases the need for labeled training data, which results in a lower annotation burden for domain experts.
